.SPECIFICATION forming part of Letters PatentNo. 744,755, dated November` 24, 1903;

Application filed December 12, 1902. Serial No. 134,970. (No model.)

To all whoml it may concer-n:

Beit known that I, EZRA W. HAsnNPELUG.,Y

a citizen of the United States of America, and a resident of East Cleveland, in the county of Cuyahoga and State of Ohio, have invent-A ed certain new and useful Improvements in Sash-Fasteners, (Oase No. 2,) of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvementsin sash-fasteners, an'd has for its object the provision of a device of this character adapted, preferably, to he formed from sheet-steel and assembled from a few simple parts so designed as most effectively to accomplish the functions of a ,sash-lock.y

My improved device is of the.type having a pivoted cam-like operating-lever for adjusting the window-sashes when cooperating with or acting upon a hook-shaped keeper,-

flat suitably-shaped springs and the coacting keeper, against which the anged vlever opcrates. These parts are stamped by suitable dies, preferably from sheet-steel of sufficiently heavy gage, the case-plate in the adopted form having an integral boss or stop formed upon its upper face for staying the operatinglever, the said lever and tubular pivot and washer being riveted together and the springs being so bent or shaped as to stay themselves in the case-plate and securely mount the operating-lever and its pivot therein.

Further particulars of construction and 0peration will be readily understood by referring to the accompanying drawings, illustrating the preferred embodiment of my invention, wherein- Figure I is a plan view of the complete sashfastener. Fig. II is a bottom view of the caseplate and the parts Inoun ted therein. Fig.

III is a vertical sectional VView on line 3 3,*Fig. I. y Fig. IV is a yfront view of thev keeper. Figs. V and VI, respectively, are side and plan views of the integral pivot and washer; and Fig. VII shows in plan and sectional views acaso-plate of modified form.

Throughout these drawings and the accomor stamped from any suitable sheet metal.

The oblong chambered case plate a is pierced near its ends by two countersunk screw-holes a2 for seating the screws by which it may be attached tothe meeting-rail of the lower sash. A boss or stop a3 is struck up from the upper face of the case-plate, which otherwise is dat, to form a Hush bearing for the operating-lever b. A circular opening provided centrally in said case-plate serves to accommodate the tubular portion of the integral pivot and washer c, which mounts said lever upon the case-plate. This operating-lever-is rearwardly flanged to aord an inclined and eccentric actuating edge or way b2 for operating the keeper d to raise and fasten the sashes.v A thu mb-piece b3 is provided by which the lever is manually moved, while lateral recesses b4 indent the front edge of the lever and accommodate the stop a3 alternatively in either of the extreme positions of the said lever. Segmental countersunk holes b5 are centrally formed in the flat portion of the lever to .receive the upper extremities c2 of the pivot c, the said extremities being upset therein after their insertion, thus making the parts practically integral.

The part c is shown in detail in Figs. V and VI of the drawings, and comprises two shouldered segmental uprights c3, extending through the case-plate to form a laterallyiattened tubular pivot for the lever and a substantially circular head or washer c4 for mounting the lever upon the case-plate. This is accomplished by means of the fiat springs IOO e e, which are of sufficient width to pivotally mount the lever closely upon the case-plate when said springs are mounted edgewise and interiorly between the top of the case-plate and the head of the pivot, as seen in Fig. III. The springs e e are C-shaped, having both their ends outwardly bent, after the manner shown in Fig. II, and together conform to the interior outline ofthe caseplate,fitiingsnugly therein, particularly at the ends, between the depending rim thereof and the depressions formed by the countersunk screw-holes a2 upon either side of the pivot and beneath its integral head or washer. By this means the springs are held securely in place without providing special parts in the case-plate to accommodate them, and accordingly this type 0f spring contributes materially to the simplicity and cheapness of the structure. Especially is this true in a stamped case-plate, since the provision of lugs or equivalent parts therein (quite common incast case-plates for retaining in position the straight flat springs) would necessitate cutting openings or depressions in the sides or top of the stamped oase-plate, which obviously would be both undesirable and difficult. It' desired, a single heavy spring might be employed, thus reducing the several component parts to four; but I prefer the arrangement herein shown. Similarly the integral tubular pivot and washer c is of simple and strong construction and in effect becomes a part of the operating-lever when united as set forth. It affords a large bearing for the operating-lever and is sti and rigid, being connected thereto at two relatively distant points. The -hooked keeper d likewise is quite elementary in form, having a chambered base d2, provided with the necessary screw-holes, and an angularlyshaped hook or extremity cl3, rising above an indentation or recess in the base. This extremity is shaped to conform to the flanged operating-lever.

When the sash-fastener is given a fine nish, I have found that the rotation of the operating-lever is liable to scratch or mar the surface of a perfectly-flush case-plate, and accordingly I have devised a modification of the latter which avoids this disadvantage and also makes the operation of said lever somewhat easier. This modification (illustrated in Fig. VII) provides a slightly-raised annular bearing-face or platform about the cent-ral opening of the case-plate, whereon the operating-lever freely turns, said bearingface CL4 being of considerably less height than the boss a3 in order that the lever may be checked by said boss or stop in the manner described.

When properly inonntedjupon the meetingrails of window-sashes, the several parts form a simple, cheap, and eective sash-fastener. The springs e e, bearing laterally upon the cut-away portions of the tubular pivot, tend to maintain the operating-lever in either of its extreme positions in engagement with the stop a3. Upon turning the operating-lever beneath the hooked extremity of the keeper the latter rides upon the eccentric flanged actuating edge b2 of said lever. The continued rotation of the lever serves to adjust the sashes so that their meeting-rails are brought into alinement and also are drawn into close engagement with each other, in which position they are locked.

Having now described the preferred ein bodiment of my invention, l desire to claim the features which I believe to be new therein, as follows:

l. In a sash-fastener, the combination with a chambered case-plate having an elevated central platform a4, of an operating-lever pivotally mounted thereon to swing above the level of said oase-plate, thereby reducing friction and avoiding the defacement of said caseplate, and a spring or springs within the caseplate adapted to swing the operating-lever to either of its normal positions, substantially as set forth.

2. In a sash-fastener, the combination with a mounting-plate, of an operating-lever, and a rigidly-attached tubular pivot part therefor, formed of sheet metal and serving to mount the operating-lever, substantially as set forth.

3. In a sash-fastener, the combination with a case-plate, of apivoted operating-lever, and a depending tubular pivot therefor; all of said parts being formed of sheet metal, and the pivot and lever being rigidly united, substantially as set forth.

4. In a sash-fastener, the combination with a chambered case-plate, of a flanged operatinglever, an integral tubular pivot and washer rigidly attached thereto, and a springmounting for the said pivot and operatinglever serving to secure them rotatably to the case-plate, substantially as set forth.
